If you have type 1 diabetes, your pancreas does not make insulin or makes very little insulin. Type 1 diabetes can affect people at any age, but commonly develops in children and young adults. People living with type 1 diabetes need daily insulin injections to control their blood glucose levels. If they do not have access to insulin, they will die.
In 2022, around 8.75 million people with diabetes were living with the condition, with 1.52 million under 20. The exact causes of type 1 diabetes remain unknown. However, research shows that the possibility of developing the condition increases slightly if a family member has it. There are also environmental factors, such as exposure to a viral infection, which can trigger an autoimmune reaction that leads to type 1 diabetes.
Type 1 diabetes cannot currently be prevented and there is no cure for the condition.
Symptoms of type 1 diabetes
The most common symptoms of type 1 diabetes include:
- Abnormal thirst and dry mouth
- Sudden weight loss
- Frequent urination
- Lack of energy, tiredness
- Constant hunger
- Blurred vision
- Bedwetting
Diagnosing type 1 diabetes can be difficult, so additional tests may be required to confirm a diagnosis.
Management of type 1 diabetes
People with type 1 diabetes require daily insulin treatment, regular blood glucose monitoring and a healthy lifestyle to manage their condition effectively.
Insulin
All people with type 1 diabetes need to take insulin to control their blood glucose levels. There are different types of insulin depending on how quickly they work, when they peak, and how long they last. The three most common ways to take insulin are with a syringe, an insulin pen or an insulin pump.
Continuous Glucose Monitoring (CGM)
The emergence of Continuous Glucose Monitoring (CGM) has been a pivotal advancement in supporting diabetes management. Unlike self-monitoring of blood glucose (SMBG), which involves finger pricking and blood drawing, CGM devices offer a more user-friendly and less intrusive solution to measure glucose levels. For people living with type 1 diabetes, CGM devices can improve quality of life and well-being by providing real-time data that helps make informed decisions about diet, insulin dosing and overall lifestyle.
The benefits of physical activity
Regular physical activity dramatically benefits people with type 1 diabetes. It improves cardiovascular health, builds strength, aids in weight management and helps manage blood glucose levels. Exercise also boosts mood, reduces stress, and increases mental well-being for a healthy lifestyle.

Healthy nutrition
People with type 1 diabetes can eat a variety of food without restrictions. The days of following strict guidelines are long gone, thanks to advancements in insulin regimens and delivery systems. However, to help keep blood glucose levels within the target range and delay or avoid diabetes-related complications, people with type 1 diabetes should eat healthy, balanced meals that include all major food groups.

Type 1 Diabetes Index
The Type 1 Diabetes (T1D) Index is a first of its kind data simulation tool that measures and maps the human and public health impact of type 1 diabetes. The Index uniquely illuminates the human impact of the condition by highlighting “missing people” and “healthy years lost” to type 1 diabetes.
The Index was developed collaboratively by JDRF, Life for a Child, International Society for Pediatric and Adolescent Diabetes (ISPAD), IDF and Beyond Type 1.
